VEHICLE ACCELERATION WHEN IN AN AIR RESTRICTION MODE
First Claim
1. A method of controlling an internal combustion engine of a vehicle, the method comprising:
- continuously sensing a position of an accelerator pedal of the vehicle;
sensing a speed of the vehicle;
removing a restriction to the air intake throttle to allow unrestricted intake airflow to the engine when the engine is operating in an air restriction mode, when one of a change in position of the accelerator pedal over a period of time is greater than a pre-defined pedal acceleration limit or the position of the accelerator pedal is equal to a pre-defined pedal limit, and when the speed of the vehicle is less than a pre-defined speed limit.

Abstract
A method of controlling an engine of a vehicle having a particulate filter and operable in an air restriction mode wherein air inflow to an air intake throttle is restricted includes determining if the engine is operating in the air restriction mode, sensing a position of an accelerator pedal, and sensing a speed of the vehicle. The method further includes removing the restriction to the air intake throttle when the engine is operating in the air restriction mode, one of a change in position of the accelerator pedal over a period of time is greater than a pre-defined pedal acceleration rate or the position of the accelerator pedal is equal to a pre-defined pedal limit, and the speed of the vehicle is less than a pre-defined speed limit.
